British retailer Sir Philip Green has a Mercedes S500, a Gulfstream jet, a 206-foot yacht and a combined net worth of more than $6 billion with his wife, Tina. But the Topshop owner doesn’t use a BlackBerry or an iPhone — instead, Green talks on a 9-year-old Nokia 6130, a model long since discontinued. “This phone has no answering machine because it’s on 24-7,” he told W magazine. Green is so loyal to the unit’s simple design — no camera, a monochrome screen — he bought the entire back stock of the obsolete 6130 in case one breaks.
